MANUFACTURE OF CUTLERY HANDLES.

EPECIPICATION forming part of Letters Patent No. 359,883, dated March22, 1887 Application filed October 10, 1885. Serial No. 180,279. (Nomodel.)

To (4% whom it may concern.-

Be it known that I, ISAAC E. MOODY, a citizen of the United States,residing at Northampton, in the county of Hampshire and State ofMassachusetts, have invented new and useful Improvements in HollowMetallic Handles, of which the following is a specification.

This invention relates to metallic handles; and it consists in animprovement in the art of making such handles for knives and similararticles, substantially as hereinafter described and claimed.

In the drawings forming part of this specification, Figure l is a sideelevation of a tableknife having a hollow handle applied theretoconstructed according to my invention. Fig. 3 is a plan view of theforged handle as it appears before it is finished and attached to theknife. Fig. 4 is a transverse section of the handle, Fig. 3, on line m:0. Fig. 2 is a similar view to Fig. 1, but showing a handle adapted tobe attached to a tang on the knife. Fig. 5 is a side elevation, and Fig.6 an end View, of a cylindrical bar of metal from which the hollowhandle is made. Fig. 7 is a longitudinal section of the bar, Fig. 5,after the latter has been bored out, making it a hollow cylinder with asolid end. Figs. 8 and 9 are similar views to Fig. 7, but showingsectional views of the tang-plugs in their ends. Fig. 10 illustrates atang-plug in plan view and in side elevation.

In the drawings, h, Fig. 1, represents in a longitudinal sectional viewthe above-mentioned improved hollow handle, having the solid butt 0,which is integral with or of the same piece of metal as the sides orshell of the handle, and the tang-plug 0, having the tang o thereon, issecured in the open end of the handle by drop-forging at the same timethat the required form is given to the handle, as shown in Figs. 1, 3,and 4, and as hereinafter described. The tang 0 is screw-threaded, andthe bolster (shown in section) of the knife or is tapped to coincidewith the said screw on the tang, and the handle is thereby screwed tothe bolster, the face of the latter and the adjoining end of the handlebeing finished in the same plane or true to each other, and therebyinsuring a perfectly-tight joint between them when screwed together, asshown.

The handle is to knife m, Fig. 2, is made in the same manner in allrespects as said handle 71., excepting that in place of the tang-plug cthe plain cylindrical plug (1 is secured in theopen end of the handle bythe means above described, by which said tang-plug is therein secured.The plug (1 is employed only when it is found preferable to form a tang,z, on the bolster of the knife, and in such cases the plug (1 is drilledand tapped, so that the handle I; may be screwed onto the screw-threadedtang z, and thus the handle besecured to the knife. Either one of theabove methods of attaching the handle to the knife is practicable; butthat shown in Fig. l is the most desirable, because it obviatespuncturing the plug and leaves an unbroken wall around the chamberwithin the handle.-

The method of making the abovedescribed handle is as follows: To producea handle whose finished surface shall partake of the characteristics ofthe surface of the finished steel knife as far as possible, suitablesteel, in the form ofa short cylinder, (1, Fig. 5, is employed, saidpiecea being about the length of the handle to be made therefrom. Thesteel piece a is first drilled out and converted into a tube or hollowcylinder, Z having the solid end 6. The metallic tang-plug c is theninserted in the open end of tube I), as shown in Fig. 8, and said partsare together heated to a proper red or forging heat, or to awelding one,and are submitted to the action of suitably-formed dies in an ordinarydroppress, whereby they are forged by a single blow of the latter to theform shown in Figs. 3 and 4. The tang-plug c and the open end of thetube 1) are thus by heat and pressure solidly united and secured oneltothe other, hermetically closing said open end of the tube b, which thusbecomes theta-ng end of the handle h. By the said action of thedrop-press on the pieces b and c the handle is completely formed, and tofinish it it is only necessary to remove the forging-fins w, cut ascrewthread on the tang 0, face the tang end of the handle, and polishthe latter.

By forming the handle h under heat and pressure, as aforesaid, the openend of the tube b, from which the handle is made, and the said tang-plugare so solidly welded together that the resultant product is a hollowhandle which,
